Even though its public land , being in someone elses blind is bad....Watch closer to the beginning of season and see if they do any work to it.....Is the slough big enough for two blinds??...Leave a note in the old blind with your name and number , just in case someone does come to brush the blind before season...Maybe its someone who hunts by himself and might want a partner...Just my two cents worth , but I'd check out every option before I took up hunting someone elses blind
